The Sum Of Two Numbers Is 36 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 36 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 36
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 36 X - Y = 5 2X = 41 |
Let's divide 41 to 2 for the first number "X" .
X/2 = 20.5
First number is 20.5
X + Y = 36
So ;
20.5 + Y = 36
Y = 36 - 20.5
Y = 15.5
Second number is 15.5
Question & Answer
The Sum Of Two Numbers Is 36 And Their Difference Is 5 : 20.5 And 15.5
